I wasn't thinking in terms of the disabling, but rather just in terms of "how frequently does this work, and how long do I have to wait after a patch to use it again". If CK2 is faster than EU IV in terms of new patch --> overhaul mod is playable turnaround, that could at least partially explain the difference. If it isn't, then that's probably not a significant factor.
I would say it's not, with possibly the exception of patch 1.12. Porting mods to new CK2 versions tends to be more work due to the larger size of the databases. Patch 1.12 changing a lot of things and patch 1.13 partially integrating bigger diplo view probably both are part of the reason for the dip from 1.11.
